Swiss Diamond has revolutionized nonstick cookware with its patented diamond reinforced nonstick cooking surface. Swiss Diamond pans start with a pressure cast aluminum base that is covered with a nano-composite coating containing up to 200,000 diamond crystals in each piece of cookware. This nano-composite coating is almost indestructible - it's safe for metal utensils and dishwashers - and diamonds are also the best natural conductor of heat, enhancing the effects of the aluminum cookware base. The pans feature ergonomically designed handles for comfort and control while cooking. Made in Switzerland, the Oval Fry Pan measures 10 by 15 inches and is perfect for large fish, steak, potatoes, or veggies. Limited lifetime warranty.
